Hisashi Iwakuma has become the second Japanese-born pitcher in major league history to throw a no-hitter, leading the Seattle Mariners to a 3-0 victory over the Baltimore Orioles on Wednesday.

Iwakuma struck out seven and walked three in throwing the first no-hitter by an American League pitcher in nearly three years. He joins Hideo Nomo, who threw two no-nos, as the only Japanese-born pitchers to accomplish the feat.

Iwakuma is the fourth pitcher to throw a no-hitter this season, joining Philadelphia's Cole Hamels -- prior to his trade to Texas -- Washington's Max Scherzer and San Francisco's Chris Heston.

Iwakuma is the first American League pitcher to throw a no-hitter since teammate Felix Hernandez tossed a perfect game against the Tampa Bay Rays on Aug. 15, 2012.
